ILLUMINATING SIGNAL.

Application filed October 22, 1923.

To all whom it may concern.

Be it known that I, Jnssn G. RosnBooM, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in Illuminating Signals, of which the following is a specification.

My present invention pertains to illuminating means for direction signals such as are used on motor vehicles, and it contemplates the provision of a series of reflectors so constructed and arranged that the direction signal will at the proper time be clearly illuminated in order to enable a person to readily and easily determine the contemplated direction of travel of the vehicle as well as the intention of the operator as to the action he will cause said vehicle to take.

Other objects and characteristic features will be fully understood from the following description and claims when the same are read in connection with the drawings accompanying and forming part of this specification in which:

Figure 1 is a view partly in section and partly in side elevation of a direction signal and my novel illuminating means secured thereto.

Figure 2 is a side elevation of a portion of the reflectors of the device and the sockets to which said reflectors are secured.

Figure 3 is an end elevation of one reflector, signal box, supporting bracket and one gear operating the box.

Figure 4: is a fragmentary view of the reflector, support and the illuminating means.

Figure 5 is a detail view of one of the sockets for the illuminating bulb and showing a modified construction of the socket.

Figure 6 is a detail view of one supporting bracket.

Figure 7 illustrates the elements of one socket as disassembled.

Figure 8 is a side and end view of the connecting device for adjoining reflectors.

Figure 9 is a detail view of one of the reflectors.

Similar numerals of corresponding parts in drawings.

My novel device is illustrated as supported on a stationary bracket 1 having the upstanding end portions 2; and adapted to act as a bearing in the aperture of the ends is a collar or flange 3. The bracket 1 may be secured in any appropriate manner on a reference designate all the views of the Serial No. 670,168.

motor vehicle for convenient manipulation of the operating mechanism of the operator.

An electric bulb is provided on the socket from which extends the wiring 5 and at its end opposite the bulb the socket is provided with threaded portion 4 that engages a threaded nut or collar 41* that is made secure to and forms a part of the supports 2; said supports being too narrow to receive a thread.

The collar i is similar to element 3 and is inserted in an opening in the support 2 as shown in Fig. 5.

Secured to the end of the socket so as to prevent interference in removal of the bulb, is a reflector 9 preferably of cone shape in cross-section that is provided with a threaded end as illustrated to engage a cap 10 having a flange to confine the lens 11. The collar a is used to mount the wheel lt on the stem of the lamp.

To the cap 10 I secure a reflector 12 which is slightly more than semi-circular in crosssection and is pitched at an angle as illustrated with respect to the lens 11 whereby the rays from the bulb will strike the reflector 12 and reflect its rays at an angle so that a perforated or transparent sign placed in front of the reflector 12 will be illuminated. Obviously such illumination is superior to that produced by placing a bulb only and not a bulb and reflector in rear of the transparent sign.

lVhen two bulbs are used in one sign, one at each end, there is a space between the two reflectors 12 12 Figure 1, which permits connection of the reflectors to the lens.

These reflectors are secured to each other by means of the spring clip 15 having the bent end portions 15.

Using the sockets 3 inserted in supports 2, as shafts, I mount a movable revolving sig nal box 13 having end walls.

I have not illustrated transparent material on the side walls of the box but I prefer that same be employed.

The signal box comprises frames 13 and a toothed gear 14: is secured on one end of the frame and rotation of the frames may be accomplished by means of the gear 14 in connection with any form of actuating gears. Manifestly transparent sides are to be formed in the frame wit-h direction signals produced in said sides.

By reference to the drawings it will be seen that I provide one end of the socket with a stud 8 that enters thebayonet slot 7 of themernber 6; I
